CLAMP.

Specification of Letters Patent.

Application filed March 19, 1912, Serial No. 684,777. Renewed November 23, 1914. Serial No. 873,645.

To all whom it may concern Be it known that 1, WILLIAM H. BownRs,

- a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented new and useful Improvements in Clamps, of which the following is a specification. v

This invention relates to clamps, especially designed for the use of workmen in the construction of buildings, the same being adapted for the temporary fastening of gage strips to an overhead beam or bearer, and embodying means for temporarily supporting and positioning the gage strips while they are being clamped to the bearer by the jaws of the device.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended. I

In the drawings: Figure 1 is a view in elevation of the clamp shown in its applied position to an overhead bearer, illustrating the strip sustaining arm in its operative position in full lines, and illustrating the inoperative position thereof in dotted lines. Fig. 2 is an edge view of the same.

The clamp contemplated in this invention embodies a pair of levers 1 and 2 which are crossed and pivotally connected at 3, and provided with inwardly extending jaws 41 adapted to bear against the gage strips, shown at 5, and hold said strips against the depending portion 6 of the overhead bearer.

Connected to one of the levers is a strip sustaining arm or bar 7 which is pivotally connected at 8 to one of said levers and supported on the other lever by means of a push pin 9, adapted to slide easily through a hole 10 in the other lever, said pin being provided at one end with a relatively large head 11, while the other end is slightly upset or expanded, as shown at 12, to prevent the pin from working entirely out of the hole 10. The hole 10 may be countersunk, if desired, to receive the expanded extremity 12 of the push pin.

Connected to the extremity of one of the levers is a flexible stay 13, shown in the form of a chain, having a fixed connection at 14 with one lever, while the opposite lever is provided with a reduced extremity 15 adapted to be inserted through any one of the links of the chain, as shown in Fig. 1, to hold the levers in fixed relation to each other, with the jaws 1 bearing firmly against the gage strips 5.

In using the clamp, the strip sustaining arm 7 is first placed in position on the pin 9, and the gage strips 5 are then applied to the overhead bearer between the jaws 4. The

levers 1 and 2 are then brought together and secured by the flexible stay 13, as clearly shown in Fig. 1. As soon as this is accomplished, the pin 9 is pushed back, so as to per mit the strip sustaining arm 7 to swing downward to the dotted line position shown in jaws set, and a gage strip sustaining barterminally connected to one lever and means on the other lever to temporarily support the free end of the strip sustaining bar so that it may be moved out of the way after the strips have been clamped against the work.

2. A clamp for securing gage strips to over-head bearers, comprising two hand levers crossed and pivotally connected and provided with inwardly extending clamping jaws, means connecting the levers for h0lding the jaws set, a gage strip sustaining bar terminally connected to one lever and adapted to be swung into and out of operative position, and a push pin having a sliding relation to the other lever and forming a temporary support for the strip sustaining bar.

In testimony whereof I alhx my signature in presence of two witnesses.

WILLIAM H. BOWERS.
